Sentence examples for slim hole from inspiring English sources

Regardless of varied radial slim hole and in-situ stress parameters, hydraulic fracture always initiates in the heel of radial slim hole.

For hydraulic fracturing assisted by single radial slim hole, smaller horizontal stress difference (3 MPa, σH/σh = 1.25) and smaller radial slim hole azimuth (15°) may guide propagation of hydraulic fractures along radial slim hole, and larger horizontal stress difference (6 MPa, σH/σh = 1.67) can sharply reduce guidance of radial slim hole.

Lady Sergeant squeezed through a slim hole in the hedge, and encouraged me to follow her.

Larger horizontal in-situ stress difference (>6 MPa, σH/σh > 1.67) hardly results in directional propagation of hydraulic fracture along radial slim hole row, and creates bigger diversion angle of fracture, and larger azimuth (>45°) of radial slim hole row reduces the guidance strength, resulting small fracture diversion radius.

The effect of annulus inclination and drill pipe rotation on the carrying capacity of drilling fluid, particle rising velocity, and pressure drop in a slim hole annulus were measured for fully developed flows of water, and for aqueous solutions of sodium carboxymethyl cellulose (CMC) and bentonite.

The technology of directional propagation of hydraulic fracture guided by vertical multi-radial slim holes is innovatively developed.

The results show that directional propagation of hydraulic fractures guided by vertical multi-radial slim holes is feasible.

The simulation results provide methods for designing directional propagation of hydraulic fractures guided by vertical multi-radial slim holes.

Affected by mutual interference from guidance of radial slim holes and controlling of horizontal in-situ stress, fractures tend to distort along fracture length and fracture height.

For hydraulic fracturing assisted by vertical multi-radial slim holes, horizontal stress difference is one of key factors influencing the directional propagation effect of hydraulic fracture.

In order to verify this technology, lots of true triaxial hydraulic fracturing simulation experiments were carried out with artificial cores, aiming at investigating the influence of in-situ stress, fracturing fluid displacement, and azimuth, diameter, number, and spacing of radial slim holes on fracture propagation.
