Abstract
The utility model provides an umbrella-opening aiding device of horizontal well logging. The umbrella-opening aiding device for the horizontal well logging utilizes a motor for driving operation. The middle part of a body is provided with a push-pull rod having an end connecting with the motor. The push-pull rod connects with a guide rail connecting with the body and a guiding wiper block flexibly. A slide block having an end connected to a switch is arranged between the body and the guide rail. A left support arm and a right support arm connected together flexibly through a hinge is arranged between the slide block and the guiding wiper block. The left support arm connects with the slide block flexibly through a hinge. The right support arm connects with the body through a hinge. A push-pull slide block connecting with the guiding wiper block flexibly fits with the right support arm. An energy storing spring is connected between a fixing pin connecting with the push-pull rod fixedly and the push-pull slide block. The left support arm and the right support arm are disposed on two sides of the push-pull rod and are arranged oppositely.
Description
Technical field
The utility model relates to a kind of oil reservoir logging instrument, particularly a kind of horizontal wellbore logging Aid for opening umbrella that utilizes driving method to carry out operation.
Background technology
In recent years, the quantity of each oilfield horizontal well sharply rises, and presses for to carry out the horizontal well production logging to understand down-hole injection and output situation.The production logging instrument that prior art is used; Its current collecting umbrella can't in full force and effectly open or close up in the horizontal well test; Reason is that current collecting umbrella muscles and bones support power is limited in addition, causes current collecting umbrella in full force and effectly not open because action of gravity causes logger serious eccentric (not placed in the middle) in horizontal well; Gently then can't normally accomplish logging tasks, heavy then possibly block to fall logger and lead to a disaster.
Summary of the invention
The purpose of the utility model is intended to overcome the deficiency of prior art; Provide a kind of and can guarantee that the horizontal wellbore logging instrument freely opens and the horizontal wellbore logging Aid for opening umbrella that closes up support arm in horizontal well for the horizontal wellbore logging instrument provides bigger supplemental support power.
The purpose of the utility model can realize through following technical measures:
The body middle part has an end to connect the pull bar of motor; Pull bar flexibly connects with the guide rail that is connected body, guiding wiper block; There is an end to be connected with the slide block of switch between body and guide rail; Be provided with left support arm and the right support arm that flexibly connects through hinge between slide block and guiding wiper block, left support arm flexibly connects through hinge and slide block, and right support arm is connected with body through hinge; The push-and-pull slide block that flexibly connects the guiding wiper block matches with right support arm, is connected with energy-stored spring between the steady pin of fixed connection pull bar and push-and-pull slide block.Left side support arm is connected through the hinge into umbrella with right support arm.
The purpose of the utility model also can realize through following technical measures:
Described left support arm and right support arm are positioned at the pull bar both sides and to being provided with; Described pull bar termination is that cylindrical leading screw is secondary, lead screw pair be connected can positive and negative direction motor rotating leading screw match; Described push-and-pull slide block is provided with the allocating slot that matches with the pusher dog of right support arm afterbody.
The utility model motor drives support arm auxiliary current collecting umbrella in horizontal well indirectly through transmission device and realizes free opening and closing.It can be for the horizontal well instrument provides bigger supplemental support power, has guaranteed that the horizontal wellbore logging instrument is reliable and effective to open and close up.Its technical scheme is the support arm that comprises with energy-stored spring interlock, and wherein, being provided with at an end of support arm can forward and reverse motor rotating, and motor drives support arm indirectly through transmission device and freely opens and close up.The utility model can freely open in horizontal well and close up support arm; To current collecting umbrella bigger supplemental support power is provided; Overcome the logger deadweight; Logging instrument is kept in horizontal hole between two parties, solved the logger current collecting umbrella and in horizontal well, be difficult to the reliable effectively technical barrier of opening and closing, guaranteed the smooth completion of afflux logging tasks and the safety of construction operation safety and logger.
