The invention discloses a two-well horizontal connected well group retreating solution mining/cavity-building method. The method comprises the following steps of (1) drilling a straight well and an inclined well to a target stratum separately, and then drilling a horizontal wellbore to connect the straight well and the inclined well; lowering a first central pipe into the straight well, and lowering a second central pipe into the inclined well and the horizontal well; and (2) carrying out solution mining/cavity-building in a sectioned mode.

The invention relates to an anal fistula plug which is insusceptible to dropping. The anal fistula plug comprises a circular table body implanting section, wherein the large end face of the implanting section is connected with one end of a plug body section; the other end of the plug body section is connected with a bottom surface of a cylindrical stitching area; the plug body section is formed by connecting more than two oblate spheroids; and the stitching area and the plug body section are made of a small intestinal submucosa or an allogenic biological material. According to the anal fistula plug, a plug body consists of a plurality of oblate spheroids, and the axial self-balancing of uniformly-distributed acting force to which the single oblate spheroid is subjected can be realized, so axial force generated by deformation stretching is generated on the integral plug body section only, and is balanced with 'rectal resting pressure' which acts on the large-end face side of the implanting section to avoid operation failure caused by the dropping of the implanting section. Numerical simulation indicates that the axial component force of the anal fistula plug under weight pressure can be reduced greatly, so that the anal fistula plug is prevented from dropping.

The invention provides a method for judging whether a gas well carries fluid normally or not. According to a liquid droplet model, a critical fluid-carrying flow formula is derived, the critical fluid-carrying flow of the gas well is calculated, compared with the actual yield of a gas producing well, if the critical fluid-carrying flow is larger than the yield, the gas well carries fluid abnormally, fluid is accumulated in the gas well, and if the critical fluid-carrying flow is smaller than the yield, the gas well carries fluid normally; if the liquid droplet model is in an oblate-spheroid shape, the projection, in the vertical direction, of the model is in a regular circular shape, and the projection, in the horizontal direction, of the model is in an oval shape. The critical fluid-carrying flow value obtained by the method can more accurately judge the fluid accumulation condition of the water-production gas well in the Sulige gas field, and compared with other kinds of calculationresults, the critical fluid-carrying flow value obtained by the method is more reliable.

A mechanism for reducing horizontal force in load measurement is presented. The mechanism includes a structure having surfaces of nonuniform radii of curvature (e.g., oblate spheroid surfaces) at both ends. The ends of the structure contact a force-sensor coupling element and a base-coupling element, forming two interfaces. Each interface includes a contact area between a convex surface and a concave surface. When a horizontal force is applied, the contact area at each interface shifts, allowing the structure to tip from the vertically aligned position that it is in when no horizontal force is applied. Compared to conventional mechanisms, the structure of the invention has a lower effective height because interfaces between oblate spheroid surfaces allow a larger angle of deflection than flat interfaces. The oblate spheroid interfaces also allow deflection to occur with less wear and tear at the interfaces compared to the flat-interfaced structures.
