The invention discloses a connected dissociator of downhole tool, which is characterized by the following: delivering joint, underbodies, downhole tool, mandrel, connected rod; extending the underbodies with cutting each round root in the course of upper body insert into underbodies; inserting the upper body into the underbodies; recovering the underbodies; suspended-connecting the upper body and the underbodies to one body; bringing the upper body, lower body and the downhole tool to work together with the connected rod; bringing the upper body, underbodies and the downhole tool upgo with the connected rod; touching cone in the inner surface of the underbodies end and the cone on the lower of the delivering joint; generating tension; extending the underbodies with the cutting round toot; losing suspend of the upper body; separating the upper body and the underbodies; submitting all tools above the upper body. This invention possesses high intensity, simple structure and simple operation.
Description
1. Technical field [0001] The invention belongs to a downhole tool of an oil production well in an oil field, and relates to a downhole tool connection separator. 2. Background technology [0002] When the piston diameter of the oil well pump on the oil field is larger than the inner diameter of the oil pipe on the pump, a disconnector is required to realize the connection and separation of the sucker rod and the oil well pump piston. There are many types of disconnectors, but there are some deficiencies, such as patent No. 96227867.x, although it can improve the carrying capacity and service life, but its structure is complicated, the processing cost is high, and the connection and separation are inflexible. 3. Contents of the invention [0003] The object of the present invention is to provide a separator with high strength, simple structure, low processing difficulty and reliable use of downhole tools. [0004] The object of the present invention is achieved in this wa...
