Abstract
The invention relates to the technical field of drilling equipment, in particular to a novel injection head gooseneck servo mechanism. The mechanism comprises a gooseneck and an injection head, wherein a rotary device is arranged between the gooseneck and the injection head, and the gooseneck and the injection head are connected in a rotary mode through the rotary device. The gooseneck is arranged on the injection head in a rotary mode through the rotary device, a coiled tubing enters the gooseneck through a roller, the gooseneck rotates under the drawing of the coiled tubing when the coiled tubing is not at the center position, and then the gooseneck can move along with the coiled tubing, the coiled tubing is prevented from bending when the coiled tubing enters the gooseneck, and the service life of the coiled tubing is prolonged; furthermore, due to the fact that the gooseneck is not provided with a horn mouth structure, overall arrangement of a coiled tubing operation machine is not limited.
Description
Technical field
The present invention relates to drilling equipment technical field, be specifically related to a kind of Novel injection head gooseneck follower.
Background technology
Coiled tubing unit is widely used in wellbore construction, at present, the injection head gooseneck structure (as shown in Figure 1) using on coiled tubing unit, it mainly comprises gooseneck 1 and injection head 2, gooseneck 1 is fixedly installed on injection head 2, in use, first enter again injection head 2 through gooseneck 1 around the continuous-tube 4 on the cylinder 5 of coiled tubing unit.
The injection head gooseneck structure of this structure has the following disadvantages:
First, because cylinder 5 has certain width, so, continuous-tube 4 is in the time walking around cylinder 5 and enter gooseneck 1, along having certain displacement on cylinder 5 widths, when continuous-tube 4 is during in eccentric occlusion position, continuous-tube 4 has certain bias angle theta (as shown in Figure 2) while entering gooseneck 1, owing to there being the existence of bias angle theta, and gooseneck 1 maintains static, cause continuous-tube 4, in the time entering gooseneck 1, certain bending can occur, and this bending also constantly change, and has seriously reduced the application life of continuous-tube 4 with the variation of bias angle theta; Secondly, the adverse effect of bringing in order to weaken continuous-tube 4 bendings, current common way is that bell-mouth structure of air 6 is set on gooseneck 1, although this bell-mouth structure of air 6 can avoid continuous-tube 4 to produce larger amount of bow in part to a certain extent, but the bending of continuous-tube 4 still exists, and bell-mouth structure of air 6 is arranged on gooseneck 1, to the integral arrangement of coiled tubing unit, particularly cylinder 5 has certain restriction to the distance layout between injection head 2.
So, need at present one badly and can either improve continuous-tube application life, do not limit again the device of coiled tubing unit integral arrangement.
Summary of the invention
The object of the invention is to: what exist for current coiled tubing unit affects the problem in application life because continuous-tube bends, provide one can either improve continuous-tube application life, do not limit again the Novel injection head gooseneck follower of coiled tubing unit integral arrangement.
To achieve these goals, the technical solution used in the present invention is:
