1. A packer system for use wells B in wells, which consisting of: a packer unit, a settling device, to settle the packer unit in the wells, and a retriever device to recover the packer unit from the well, thereby converting a production pipe system in an insertable production system, maintaining production levels while reducing operating times and costs, where the packer unit settles due to an effect of a hydraulic pressure that induces a mechanical displacement towards packer's mobile components by means of the settling device, said packer unit consisting of; a first mandrel, a safety ring, a release connection element, an upper safety retainer, a seal holder, a lower safety retainer, a sealing element, an upper compression element, an anchor element, a lower compression element, an anti-friction ring, an anti-friction retainer, a lower connector, a set of first security pins, a set of second security pins, a set of first breakout pins, a set of second breakout pins to hold the first mandrel to a connection release point and the lower safety retainer, a set of O-rings seals, and at least one Allen stud, wherein;
said mobile components of the packer unit consisting of; the upper safety retainer, the safety ring, the lower safety retainer, the sealing element, the upper compression element and the lower compression element, and these said-moving elements are activated by an induction effect of hydraulic pressure in displacement mechanically towards the mobile components of the packer unit, achieving fixing and sealing to a production pipe;
said at least one Allen stud does not have a function of breaking during the operation of the system, its function is to allow a fixation between the lower compression element and an antifriction element,
the second breakout pins set hold the first mandrel to the connection release point and the lower safety retainer,
the sealing element maintains the seal between a well pipe and a packer, the safety ring keeps an anchoring system and the sealing element fixed, guaranteeing hermetic sealing in a production pipeline, wherein said anchoring system comprises; the anchor element, the upper compression element and the lower compression element,
the anchor element allows anchoring between a production pipe and the packer unit at a programmed depth,
the first mandrel provides internal support to the packer unit, in particular in relation to the sealing element, the seal holder, the lower safety retainer, the upper compression element, and the lower compression element of the packer unit respectively, and the anchor element,
the release connection element has a release mechanism which, when positioned with the retrieval device, enables an internal release mechanism to be activated and can retrieve the packer unit,
the upper safety retainer in conjunction with the safety ring allows a settle of the nchor element and the packer unit sealed, through the displacement of an assembly due to an internal movement of the settling device due to the hydraulic pressure exerted in the well, received directly in an upper cup and in a lower cup,
the seal holder allows internal sealing between the first mandrel and the seal holder itself, in addition to being a support for the sealing element, a pair of O-rings is provided between the first mandrel and the seal holder,
the lower safety retainer in conjunction with the upper safety retainer, allows the movement of the anchor element and the sealing element, the lower safety retainer has a thread that will be screwed together with the upper safety retainer,
the upper compression element and the lower compression element activate the anchoring system to anchor the packer unit,
the lower compression element has holes to allow the second security pins set,
the anti-friction ring prevents or minimizes friction between the anti-friction retainer and the lower connector,
the anti-friction retainer holds fixed the anti-friction ring and the lower connector,
the lower connector, connects the packer unit to a stator of a conventional PCP and allows to avoid a backspin effect,
the set of first security pins and the set of second security pins are not designed to break, they only function is as a guide for the upper compression element and the lower compression element, and also to support and guide the anchor element, and also connect the anchor element to the upper compression element,
the set of second security pins connect the anchor element to the lower compression element,
the set of first breakout pins connect the release connection element to the first mandrel, and,
the O-rings set are seals to prevent packer unit internal leakage.
