Description
Technical Field
The utility model relates to a well pipe device, concretely relates to conveniently establish well pipe device with what well casing was extracted when the well construction was accomplished.
Background
The well building equipment consists of a GP drilling truck, a knocking cap, a well pipe and a throwing head. Wherein one end of the well pipe is an external thread, the other end of the well pipe is an internal thread, and the two well pipes are connected in a screwing mode. When the well is built, the bottom end of the well pipe is sleeved with the abandoning head, the top end of the well pipe is sleeved with the knocking cap, and the well pipe is inserted into the ground in a mode of vertically knocking downwards by using the GP drilling rig. Due to continuous knocking, the thread at the joint of the lowest well casing and the upper well casing connected with the lowest well casing is easy to wear. The two well pipes will be separated by wearing to a certain extent. FIG. 3 is a schematic view of the overall well pipe structure of the prior art. Fig. 4 is a partially enlarged view of fig. 3. There are no recesses and pull tabs in figures 3 and 4, so that when the well is set up and the casing is pulled out, the lowermost casing section remains in the ground and cannot be removed. The utility model discloses to solve this phenomenon, can practice thrift the cost, can avoid the wasting of resources again.
