The utility model discloses a kind of suction grain pipe offset suction grain machine, suction grain device and suction grain pipe are arranged on walking device, suction grain pipe is connected on rotating seat, can rotate around the center of rotating seat, suction grain pipe and rotating seat are offset in the angle position inclined outer side of suction grain device, suction grain pipe can rotate in the space range of adjacent two side surfaces of suction grain device around rotating seat center.The suction grain pipe and rotating seat of the utility model are offset in the angle position inclined outer side of suction grain device, increase the working surface range of suction grain, suction grain is more convenient and fast, less time-consuming, improve the efficiency of suction grain, reduce the requirement to space volume, more convenient to walk flexibly, also more convenient to store in warehouse, reduce storage cost.

The application discloses a conjugated crosslinking monomer, a solid-phase-free drilling fluid thickening agent, and a preparation method and application thereof. The conjugated crosslinking monomer has a stereoscopic alkyl structure and a conjugated diene structure, and is shown in the following formula. The conjugated crosslinking monomer is prepared by synthesizing an alkenyl compound with an adamantane compound in the presence of a catalyst. The conjugated crosslinking monomer is reacted with an alkenyl amide and an alkenyl sulfonic acid to obtain the solid-phase-free drilling fluid thickening agent. The thickening agent has good temperature resistance and salt resistance, and can improve the suspension and rock carrying performance of a clay-free drilling fluid system in a medium-deep well.
